The testo 635 offers the possibility of testing and analyzing air humidity, material moisture, U-value and the dewpoint in compressed air systems.
Please Note: The instrument can only be commissioned with a probe. These are available separately.
In addition to all the other measurements, the testo 635-2 temperature and moisture meter can also display min, max and mean values and calculate the dew point difference between the indoor air and the surface of the wall. This allows you to analyze levels of moisture at ceilings and walls. Individually configured characteristic curves ensure that the material moisture content is displayed reliably.
Both the meter and the menu guide are simple and comfortable to use. A backlit display allows you to read the measurements in the dark or poor lighting and a strong protective case protects the meter effectively against any accidental knocks and bumps.Saving, transferring and printing out data
Save measuring sites and allocate the measuring data to the relevant site. Create individual user profiles to perform parallel long-term and material moisture measurements. Save up to 10,000 readings – individual measurements and measurement series – to your meter. The USB cable in the scope of supply can be used to connect your moisture meter to your PC or laptop and the software allows you to log and archive your measuring data comfortably and easily.
Ideal for the following applications:
NOTE: a sensor (not in scope of supply) is required to operate the meter.
